Reclining mechanisms of vehicle seat

摘要

A seat reclining mechanism of a vehicle seat (1) includes a seat reclining device (10) that is capable of adjusting and locking a rotational position of a seat back (2), and a memory device (20) that is arranged and constructed to memorize an original rotational position (P) of the seat back (2), so that the seat back (2) can be returned from a desired tilted position (P') to the original rotational position (P). The seat reclining device (10) rotatably connects the seat back (2) to a fixed element such as a seat cushion (3). The seat reclining device (10) can be switched between a locked condition in which the seat back (2) can be prevented from rotating and an unlocked condition in which the seat back (2) is capable of freely rotating. The seat reclining device (10) in the locked condition is capable of withstanding a rotational force applied to the seat back (2) from a passenger that is sitting on the seat (1). The memory device (20) is radially juxtaposed to the seat reclining device (10) and releasably engages the seat back (2) and the fixed element (3).
